POWER TRANSMISSION CONTROL DEVICE FOR VEHICLE
DRIVE
October 23, 2013
A manual transmission of the present apparatus has an EV travel gear position (the 1-st gear) for EV travel performed through use of only drive torque of a motor connected to the output shaft of the transmission, and EG travel gear positions (the 2-nd gear to the 5-th gear) for traveling through use of drive torque of an engine transmitted via a clutch. In the case where the EV travel gear position (the 1-st gear) is selected after a clutch pedal has been depressed, a MG torque is thereafter controlled on the basis of an accelerator opening and a clutch stroke, so that the vehicle starts (normal start control). Meanwhile, in the case where the EV travel gear position (the 1-st gear) is selected without the clutch pedal being depressed, the MG torque is maintained at zero, and a warning is provided to a driver. Thus, it becomes possible to provide a power transmission control apparatus for an HV-MT vehicle which allows EV travel and prompts the driver to operate the clutch pedal if the driver operates the shift lever without operating the clutch pedal.
